I have that photofact folder but it shows models 16" and up.. Doesn't say anything about the 12T2 model.. Looking at the parts list, L23 is the Horiz Freq coil which points to a coil that should be next to the Horiz Drive control on the underside and the coil next to it is an A.F.C. coil, but obviously it's showing a different chassis.. Or unless the Horiz drive control is the Horiz Freq control, and that's all the way up, nor does it change the pattern of the screen when adjusting or make the ringing noise of the HV... Also on the top of the chassis next to the HV cage are the two flathead adjustments and the square can which is sound, one according to the sams one is Horiz Lin and other is Sound IF...
